Descrizione

Elastomer dog couplings clamping with grub screw of German company Norelem is manufactured of first-rate quality materials and is renowned for its exceptionally functional features and outstanding quality, evidenced by certificates ISO 9001 2008, RoHS, REACh and I-Q Net.Norelem offers a wide range of products which are suited for various applications. Brand products are used in machine building, plant engineering applications and other areas.
Material:Spider polyurethane hardness Shore 98A.Hub aluminium.Version:Bright.Note:Clamping the hub with a grub screw is a cost-effective alternative to the elastomer dog couplings with radial clamping hub (23022). Short mounting times.The couplings can be mounted completely assembled or plug-in mounting is also possible. Lightly oil the spider to ease assembly. Take note of the required tightening torque for the grub screw. To ease removal we recommend milling a flat on the shaft.Assembly:The shaft to hub bore fit is a transition fit. The play should be min. 0.01 mm and max. 0.04 mm i.e.shaft: Ø 6 f7hub: Ø 6 H8.Bores smaller than D1/D2 min. are possible, however an optimal transfer of the couplings nominal torque is no longer guaranteed.On request:Hub bores D1 and D2 with separate tolerance class or range.Drawing reference:1) elastomer spider
